Sorry I can't help you, but I just want to say that in most melee maps, mins aren't stacked. If you are trying to make a Fastest map, don't post it here because ppl at SEN don't play BGH maps.
Listen to Pekkel. You're totally at the wrong place if you want to make stacked minerals.
Go away, please.
I don't even know how, and don't want to know it either.
